bug#49999: 27.2; save-mark-and-excursion does not save mark-active

[Peter Münster]

Hi,

It seems, that save-mark-and-excursion does not restore the mark state.

Here is a test function:

(defun my-test-func ()
  "Test if save-mark-and-excursion is working."
  (interactive)
  (with-current-buffer "test-buf"
    (save-mark-and-excursion
      (goto-char (point-min))
      (add-face-text-property
       (point) (1+ (point)) (list :background "orange")))))

Test case:
- "emacs -Q"
- evaluate my-test-func
- open a new buffer "test-buf"
- type some characters
- mark a region somewhere
- M-x my-test-func

Result: point is restored, but mark-active is nil.

Kind regards, Peter
